NFC Applications

NFC, as a popular near field communication technology in recent years, has a wide range of applications. NFC applications can be roughly divided into three basic types. Let me take you to these three basic application types below.
1. Payment application
NFC payment applications mainly refer to applications that simulate bank cards and all-in-one cards on mobile phones with NFC functions. NFC payment applications can be divided into two parts: open-loop applications and closed-loop applications.
The application of NFC virtualized into a bank card is called an open-loop application. Ideally, a mobile phone with NFC function and an analog bank card can be used as a bank card to swipe the mobile phone on POS machines in supermarkets and shopping malls. However, it cannot be fully realized in China at present. The main reason is that NFC payment as an open-loop application has a tedious industrial chain, and the game between the interests of card vendors and solution providers and the industrial structure is very complicated. As far as the current domestic NFC open-loop application environment is concerned, due to the game of various interests, the NFC open-loop payment application has missed the best opportunity before the popularization of mobile payments such as Alipay and WeChat payment, and it is extremely difficult for NFC open-loop payment to continue. Develop alone. Its development only seeks to connect and bundle with Alipay and WeChat Pay, as a means of assisting Alipay and WeChat Pay for identity authentication, can it have a place in future mobile payments. (Currently in a bundled state)

2.NFC swiping POS machine
The application of NFC analog card card is called closed-loop application. At present, the development of closed-loop NFC applications in China is not ideal. Although the NFC function of mobile phones has been opened in the public transportation system of some cities, it has not been popularized. The fundamental reason is the existence of card issuance for profit in the all-in-one card system based on cards. System integrators and operators (transit groups and schools, etc.) can obtain huge profits in issuing cards. Therefore, although Xiaomi and other mobile phone companies have piloted the NFC bus card function of their mobile phones in some cities, they generally still need to open a service fee. But I believe that with the popularity of NFC mobile phones and the continuous maturity of NFC technology, the one-card system will gradually support the application of NFC mobile phones, and closed-loop applications will have a bright future.

3. Security application
NFC security applications are mainly to virtualize mobile phones into access control cards, electronic tickets, etc. The NFC virtual access card is to write the existing access card data into the NFC of the mobile phone, so that the access control function can be realized by using the mobile phone with the NFC function block without using a smart card. The NFC virtual electronic ticket application is that after the user purchases the ticket, the ticketing system sends the ticket information to the mobile phone. The mobile phone with NFC function can virtualize the ticket information into an electronic ticket, and you can directly swipe the mobile phone at the ticket check. The application of NFC in security systems is an important field of NFC applications in the future, and the prospects are very broad. The application of NFC in this field can not only save operators' costs, but also bring convenience to users. Using mobile phones to virtually replace physical access control cards or magnetic card tickets can reduce the production costs of both to a certain extent. At the same time, it is convenient for users to open and swipe cards, improve the degree of automation to a certain extent, reduce the employment of card personnel and improve service efficiency.

4. Label application
The application of the NFC tag is to write some information into an NFC tag, and the user only needs to wave the NFC tag with an NFC mobile phone to get the relevant information immediately. For example, businesses can put NFC tags containing posters, promotional information, and advertisements at the door of the store. Users can use NFC phones to obtain relevant information according to their needs, and can log in to social networks and share details or goodies with friends.

Although the application of NFC tags is very convenient and the cost is very low, the application prospects of NFC tags are not optimistic due to the popularity of mobile networks and the gradual popularity of QR codes. Because compared with NFC tags, the QR code only needs to be generated and printed into a small image, which can be said to be almost zero cost. The information provided is as rich as NFC, and it is easy to replace the use of NFC tags.
